Plot out y= x^2 - x - 2 for values of x from -3 to +3 and label the turning point

x y-3 10-2 4-1 00 -21 -22 03 4
And then be able to plot out these points on a simple graph.
The x-coordinate of the turning point is half way between the two points at which the curve crosses the x-axis. Insert x-coordinate back into equation to work out y value and label it. In this example the turning point is at (0.5,-2.25)
